Suitable for:

Shiseido HAKU Refiner serum works on several fronts at once: moisturizing, softening the stratum corneum, and preventing pigmentation. It softens the stratum corneum, helping moisturizing and brightening ingredients penetrate more deeply, prepares the skin for subsequent products, and supports its clarity and radiance.

Active ingredients and their effects:

4MSK (potassium 4‑methoxysalicylate) is an active brightening ingredient that regulates melanin formation. It helps prevent dark spots and freckles, maintains an even skin tone, and imparts a translucent radiance.
Dipotassium glycyrrhizate is an anti‑inflammatory ingredient derived from licorice root. It soothes irritation, reduces skin sensitivity, and helps maintain a healthy appearance.
Trimethylglycine (betaine) is an amino acid–derived humectant that retains moisture, softens the stratum corneum, and promotes its elasticity.
CE complex stimulates renewal processes and helps stratum corneum cells mature evenly, resulting in firmer, softer skin with a healthy glow.

Regular use of the serum makes your skin look more even, smoother, and more radiant.
